Abstract
Optimization of the..... A computation method which analyzes bladed disk assemblies with different types of underplatform dampers and a general formulation of the contact conditions that includes a spatial contact mdoel consisting of a number of discrete point contact elements that include tangential as well as normal relative displacements to study spatial blade vibrations was made. Thus, the analysis of a tuned system consisting of 16 identical blades showed the effectiveness of the different damper types for different spatial vibration modes under varying excitation amplitudes and engine orders. It was shown that the cylindrical damper works very well in the case of sufficient relative displacements within the friction contacts.
